How to create such a layout in java (photo inside)?

Question

Java

This is located on a
JPanel
I understand that TitledBorder is used
But I can't write the same. It turns out crooked and not as it should be. I will be very grateful if you write.
I use the following declarations;

JLabel b11 = new JLabel("b11");
  JLabel b12 = new JLabel("b12");
  JLabel b13 = new JLabel("b13");
  JLabel b21 = new JLabel("b21");
  JLabel b22 = new JLabel("b22");
  JLabel b23 = new JLabel("b23");
  
  JTextField b11_i = new JTextField();
  JTextField b12_i = new JTextField();
  JTextField b13_i = new JTextField();
  JTextField b21_i = new JTextField();
  JTextField b22_i = new JTextField();
  JTextField b23_i = new JTextField();
